Following query shows that architectures that don't provide asm/set_memory.h don't use set_memory_...() functions. $ git grep set_memory_ alpha arc csky hexagon loongarch m68k microblaze mips nios2 openrisc parisc sh sparc um xtensa Following query shows that all core users of set_memory_...() functions always take returned value into account: $ git grep -w -e set_memory_ro -e set_memory_rw -e set_memory_x -e set_memory_nx -e set_memory_rox `find . -maxdepth 1 -type d | grep -v arch | grep /` set_memory_...() functions can fail, leaving the memory attributes unchanged. Make sure all callers check the returned code.
